CS 30 vs Humboldt 30: the short version
- The CS 30 and Humboldt 30 are close in length (30.0 ft9.14 m vs 30.0 ft9.14 m ).
- The CS 30 is heavier, displacing about 58% more, which usually means a steadier but slower-to-accelerate hull.
- On sail area/displacement the Humboldt 30 carries the more powerful rig (27.3 vs 18.5), favouring lighter-air performance.
- The CS 30 scores higher on the Brewer comfort ratio, suggesting an easier motion in a seaway.
- By the capsize screening formula the CS 30 rates better for offshore work (2.05 vs 2.45).
Ratios are guidelines computed from published specs; condition, layout and gear matter as much as the numbers.
